24FC01-E/ST

Memory IC Overview

The Microchip Technology 24FC01-E/ST is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) housed in an 8-lead TSSOP package. It features a 2-wire I2C compatible serial interface with a maximum clock frequency of 1 MHz when operating between 1.7V and 5.5V. The device utilizes low-power CMOS technology, supporting a supply voltage range from 1.7V to 5.5V. It operates within the extended industrial temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication for efficient data transfer
• Operates on a single power supply ranging from 1.7V to 5.5V
• Includes hardware write protection via the WP pin to secure memory data
• Features Schmitt trigger inputs and noise filtering for reliable operation

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in sensor modules
• Device identification and serial number storage

Memory IC Procurement Notes

Verify that the ordering suffix 'E' confirms the Extended temperature grade (-40°C to +125°C) and 'ST' specifies the 8-lead TSSOP package. Confirm the specific revision level against the manufacturer's datasheet DS20001711M to ensure compatibility with system requirements. Check for automotive AEC-Q100 qualification if required by the application environment.

Memory IC Selection Notes

Select this component when a 1 MHz I2C interface speed is necessary compared to standard 400 kHz devices. Ensure the design supports the full 1.7V to 5.5V supply range, as lower voltages may restrict clock speeds. Verify that the 8-byte page write buffer aligns with the host controller's data handling capabilities to prevent address pointer rollover errors during bulk writes.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA01 and 24LC01B but offers superior bus performance through its 1 MHz clock capability. The device is designed for applications demanding fast access times and robust noise immunity in space-constrained surface-mount designs.

Memory IC Replacement Considerations

Direct functional substitutes include the 24AA01 and 24LC01B, though these are limited to 400 kHz operation. For higher speed requirements, verify availability of other 24FC01 variants with different packaging options such as MSOP or DFN.
